Artisanal miner arrives to pan for diamonds, which fuelled the 1991-2002 civil war, in the town of Koidu in eastern Sierra Leone, April 22, 2012. The U.N. war crimes court trying Charles Taylor for atrocities in Sierra Leone will deliver its verdict on Thursday. Sierra Leone's 11-year conflict from 1991-2002 left over 50,000 dead and became a byword for gratuitous violence, especially the amputation of limbs. A decade later, the West African nation is peaceful, but among the world's poorest. It is due to hold elections in November. Picture taken April 22, 2012.
